Well, I spoke too soon.

Just now I've finished refactoring the code and the program is
now 64-bit clean.  It runs without problem on my pure 64-bit system.

Thanks, Greg, for your input.  It got me to thinking about the
initial storage of the pointer values in the imageType structure.
In the original code they were stored in an array of 32-bit integers.
I thought if I simply changed the type to an array of 64-bit integers
the code might work -- and it did!  (Changing one other value from 32-bit
to 64-bit was also necessary.)

In case any are interested, the original source for the peiHalfTone
package can be found here:

Thanks again for the input.  I was truly stuck and the response
provided much needed insight.
